search for: aritmetic

I have a dataframe. Let's suppose that i have two columns. The first one contains height, the second one contains eye color that can be Green, Blue or Brown. I want to calculate the aritmetic mean of the height only for those people who have Blue eyes. How can I do it? Thank you for your availability. -- View this message in context: http://r.789695.n4.nabble.com/Mean-Help-tp4648000.html Sent from the R help mailing list archive at Nabble.com.

I like the idea, but I find the name confusing; I think it should have `llvm-c` or `c-api` somewhere in the name. This could also serve as a simple example of using the API. -- Sean Silva On Mon, Sep 23, 2013 at 4:00 PM, Anders Waldenborg <anders at 0x63.nu> wrote: > Moving this to llvmdev. > > On Fri, Sep 20, 2013 at 08:26:41AM +0200, Anders Waldenborg wrote: > > >

hi ?integer says: Note that on almost all implementations of R the range of representable integers is restricted to about +/-2*10^9: 'double's can hold much larger integers exactly. I am getting very confused as to when to use integers and when not to. In my line I need exact comparisons of large integer-valued arrays, so I often use as.integer(), but the above
